Her Sister's Shield: A Titan's Fury

“Alex Ashworth, a financial titan operating from Europe, focused on her family's legacy. Her world shattered when a coded distress signal came through: her younger sister, Chloe, was trapped on a high-stakes gambling yacht, "Poseidon's Pearl." Chloe, already vulnerable, watched as everything-her money, family heirlooms, even the last of her shares-was systematically stripped away. Then came the ultimate cruelty: terrified and humiliated, Chloe was forced to sign a contract to sell her incredibly rare Rh-null blood type. It was more than just a game; it was a calculated plot orchestrated by the smug Tiffany Miller and her cronies to utterly destroy Chloe, usurp her inheritance, and leave her broken. Alex felt a terrifying, cold fury at the public humiliation and the exploitation of her sister's unique vulnerability. How could anyone be so ruthlessly malicious, so intent on tearing down a defenseless girl for selfish gain? Just as Chloe prepared to concede, a silent, matte black card-an "Obsidian Circle" with rumored unlimited credit-appeared. Then, Alex Ashworth herself emerged from the shadows, her very presence commanding silence, ready to unleash the full force of her family's power. Now, the game was on her terms.”
